The film seems to start with a fight then, with the mention of 'grapple' and, potentially, head kicks suggesting something MMA shaped rather then boxing.

From the words I can pick out it sounds like Lara is sparring but initially getting whupped while her trainer looks at his phone. She berates him, takes a beating and then falls to the mat before getting up and destroying her opponents.

I'm extrapolating a bit here but it fits what words are visible, and the tempo of an average opening scene - Lara makes a strong, heroic appearance, faces defeat and then fights back. Loud music plays, titles roll... It's a good clear way of setting up the character.

If you can pick out any other words let me know and I'll update the 'script'.
